Tinctura Croci Sativi. Edin. Tincture of Saffron

"Take of English saffron, cut in shreds, one ounce; proof spirit, fifteen ounces. Digest for seven days, and filter through paper."

This tincture contains volatile oil, extractive, and poly-chroite, the colouring matter of the saffron. It is stimulant and diaphoretic, but its chief value perhaps arises from its colour.

Tinctura Cubebae. Lond. Tincture of Cubebs

"Take of cubebs, bruised, Jive ounces; rectified spirit, two pints. Macerate for fourteen days, and strain."

Tinctura Piperis Cubebs, Dub. Tincture of the Cubeb

"Take of cubebs, four ounces; proof spirit, two pints. Macerate for fourteen days, and filter."

If the object in this preparation is to separate the active principle of the cubebs, so as to concentrate its power, the proportion of the cubebs is too small, half an ounce of the tincture being equal only to a moderate dose, namely, half a drachm of the powder. The dose should be at least f 3 ij.

Tinctura Digitalis. Lond. Tincture of Foxglove

"Take of foxglove leaves, dried, four ounces; proof spirit, two pints. Macerate for fourteen days, and filter."

Syn. Teinture de Digitale (F.), Fingerhautinktur (G.), Tintura di Digitals porporrina(I.).

Dublin.

"Take of foxglove leaves (the larger ones being rejected), dried and reduced to coarse powder, two ounces; proof spirit, a pint. Digest for seven days, and filter."

Tinctura Digitalis Purpurae, Edin. Tincture of Foxglove

"Take of foxglove leaves, dried, one ounce; proof spirit, eight ounces. Digest for seven days, and filter through paper."

This is the best and most convenient form for exhibiting: foxglove. When the leaves are recently dried, the tincture contains digitalia, the alkaloid principle on which the virtues of the plant depend, and has the advantage of preserving these virtues unimpaired for any length of time. The dose should be x. at first, and gradually increased, the same cautions being necessary as in the exhibition of the plant in substance.

Tinctura Galbani. Dub. Tincture of Galbanum

"Take of galbanum, cut into small pieces, two ounces; proof spirits, two pints. Digest for seven days, then filter."

It is used in the same cases as tincture of assafoetida; but, if less nauseous, it is also less powerful.

Tinctura Gallae. Lond. Tinctura Gallarum, Edin. Dub. Tincture of Galls

"Take of galls in powder, five ounces (two ounces, Edin. four ounces. Dub.); proof spirit, two pints (sixteen ounces, Edin. two pints, Dub.). Macerate for fourteen days, then filter."

Proof spirit dissolves both tannin and gallic acid; consequently this tincture contains all the astringency of the galls. It is fully as useful as Ruspini's styptic, which is a solution of gallic acid in weak spirit, with minute quantities of sulphate of zinc and extract of opium. The dose of this tincture is from xx. to f 3 ij.
